Abstract：Study was carried out on the nature and origin of the flat spots in flash- welded seams of the rails by the technique of failure analysis.It was detected that the flat spots are originated from the coalescence of silicate inclusions which are formed in the process of flash-welding and are closely related to the welding technical specification. 收稿日期: 1987-01-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 郑恩贵 田继丰 吴悦魁 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1987/V23/I1/126 1 A C,1949;386-399 2 Nippes E F.Savage W F.Grotke G.et al.Weld J,1957;36:192-216 3 Riecansky V.Lucas W.Weld Res Int,1974;4(4) :1-27 4 Wuppermann G T.Stahl Eisen,1971;91:1239-1249 5 Sullivan J F.Weld J,1971;50:213s-221s 6 Sequires I F.Br Weld J,1958;15:610-620 7 东方锅炉厂,焊接,1975;(2) :4-6 8 Welding Handbook,7th ed,1980Z No related articles found!
